Numerical order refers to the arrangement of numbers in a sequence from the smallest to the largest. This organization helps in understanding and comparing values easily. For example, the numbers 3, 7, and 1 can be arranged in numerical order as 1, 3, and 7. In addition to whole numbers, numerical order can also apply to fractions, decimals, and negative numbers. For instance, the numbers -2, 0.5, and 1 can be arranged in numerical order as -2, 0.5, and 1. This concept is essential in mathematics and everyday situations, such as sorting data or organizing items.
